Abstract: pMUTs (piezoelectric micromachined ultrasonic transducer) have attracted much attention as transducers that have a good acoustic impedance matching with air and water medium. Although MEMS ...

Abstract: This work presents a flexible 3 × 3 piezoelectric micromachined ultrasonic transducer (PMUT) array designed for reconfigurable air-coupled object detection. The array operates at 230 kHz ...

Structures are used for piezoelectric energy harvesters as a way of redirecting the path of an inputted force so that the piezoelectric element can better convert the mechanical energy to electrical ...
